MPEG stands for Moving Picture Experts Group. The group
has developed compression standards that help make
high quality audio and/or video available over the Internet
with 1/20th of the download time.

The audio files end in the extension .wav. The video files end
in the extension of .avi. Your operating system must have
the appropriate drivers installed to hear and see these files.
If you have a newer system, you should be able to
experience these types of files automatically.

Many browsers are set-up to start streaming these
files as soon as you click on the link; however,
if your connection is less than a 128Kbps, you may experience
choppy playback. In this case, you should hit your
pause button until the file is most of the way downloaded
onto your machine.
